Indicators
are auxiliary tools for conducting a technical analysis of the market. One of
the easiest to use is the RSI indicator, which is often used by newcomers to
Forex. Welles Wilder introduced this tool to the general public over 40 years
ago.
The
abbreviation means “relative strength index”, but experts say that this is not
the most appropriate name for the indicator. The thing is that it shows not the
relative strength between compared instruments, but the inner strength of a
particular tool. In other words, the indicator displays the speed and amplitude
that characterize price action. By correctly interpreting signals, a trader can
predict the strength of a trend and the probability of its reversal.
Today the Relative Strength Index is part of almost any software for technical analysis of the market.
RSI is available by
default in MT4 and MT5 trading terminals.
The main
variable for the calculation is the timeframe. When talking about RSI, Welles
Wilder argued that it was best to use a two-week period. However, traders
rarely stick to classical decisions nowadays, so the analysis can be performed
with any set period.
The shorter the selected period the more
sensitive the tool. If you do not have much experience with RSI, it is better
to opt for long periods.
The
indicator line on the chart ranges from 0 to 100. It demonstrates how the price
has changed after a certain number of candles (depending on the set period).
When
trading with RSI, you should not focus only on the 100 value. The following
values are also important:
The above
should not be considered the ultimate truth. You need to correctly interpret
RSI signals and pay attention to the readings of other technical analysis tools.
To be able
to make the best possible decision, experienced traders recommend testing RSI
on different timeframes. For example, the indicator may indicate that an asset
is oversold on a ten-minute chart, while it may be overbought on a three-hour
chart. In this case, you should favor the data of the larger timeframe as the
most objective.
Strictly follow your trading strategy. If the
indicator suggests entering a trade, do not hesitate! Only strict adherence to your
own rules will reduce losses and increase profits.
The most
important thing is to always remember that there are no Forex indicators that are
never wrong. That is why it is so important to use simultaneously not one tool,
but several, comparing their signals and eliminating unnecessary noise.
